Determination of radium 226Ra. Emanation technique ICS 73.020 D14 National Standards of People's Republic of China Replacing GB/T 13073-1991 Rock samples 226Ra measured emanation method Issued on. 2010-11-10 2011-02-01 implementation Administration of Quality Supervision, Inspection and Quarantine of People's Republic of China Standardization Administration of China released ForewordThis standard replaces GB/T 13073-1991 "rock sample analysis 226Ra Emanation technique." This standard compared with GB/T 13073-1991, the main changes are as follows. --- A standard specification title; --- Increased alert, warnings; --- Provision increases the processing of waste; --- Deleted directory; --- Simplifies the measuring instruments; --- Corrected some errors. The standard proposed by the People's Republic of China Ministry of Land Resources. This standard by the National Standardization Technical Committee of Land and Resources. This standard is drafted by. National Geological Experimental Test Center. This standard was drafted. Nuclear Industry Beijing Institute of Geology. The main drafters of this standard. Wu Zhaohui, Li-kun. This standard replaces the standards previously issued as follows. --- GB/T 13073-1991. Rock samples 226Ra measured emanation method Warning. Use of this standard shall have a person experiences regular laboratory work. This standard does not point out all possible security issues. Users have the responsibility to take appropriate safety and health practices and to ensure compliance with the conditions relevant national regulations.1 ScopeThis standard specifies the method in rock samples emanation measurements of 226Ra. This standard applies to rock samples, soil samples measurements of 226Ra. Biological samples and other solid samples decompose properly and radium After enrichment, it can also refer to use. Measurement range. barium sulfate - disodium edetate (EDTA disodium) law ≥9.0 × 10-9Bq/g, barium - hydrochloric law ≥1.8 × 10-2Bq/g.2 Normative referencesThe following documents contain provisions which, through this standard reference and become the standard terms. For dated references, all subsequent Amendments (not including errata content) or revisions do not apply to this standard, however, encourage the parties to study under this agreement is standard Whether the latest versions of these documents. For undated reference documents, the latest versions apply to this standard. GB/T 6379 (all parts) of measurement methods and results Accuracy (trueness and precision) GB 9133 Classification of radioactive waste GB 14500 radioactive waste management Principle 3 3.1 Method summary Obtained by measuring the 222Rn 226Ra content. Wherein the preparation of rock samples decomposition and 226Ra solution include. alkali fusion - barium sulfate Coprecipitation - dissolution method disodium edetate and alkali fusion - barium carbonate coprecipitation - hydrochloric acid dissolution method. Two methods can be arbitrarily choose to use. 222Rn It was determined by scintillation emanation method. 3.2 Barium sulfate - disodium edetate law The samples were sodium hydroxide, sodium peroxide mixed reagent at 650 ℃ melted, extracted with water, acidified with hydrochloric acid. Barium sulfate coprecipitation enrichment radium, Then diethylamine edetate dissolved in a small volume to give a clear solution, into the diffuser, closed several days accumulation of radon, air wash with making of radon Then transferred to scintillation cell 50min from the solution in the measurement of indoor radon monitor, compared with the standard solution of radium, radium content in the samples. 3.3 barium - hydrochloric acid method The samples were sodium hydroxide, sodium peroxide, barium chloride anhydrous sodium carbonate and a mixed reagent at 650 ℃ melted, extracted with water, filter paper. With hot hydrochloric acid precipitate was dissolved in the original beaker, into the diffuser, closed several days accumulation of radon below 3.2 in the same manner with the measurement and calculation.4 ReagentsUnless otherwise stated in this section, both in the analysis using analytical grade and distilled water or equivalent purity water in line with national standards. 4.1 sodium hydroxide. 4.2 sodium peroxide. 4.3 anhydrous sodium carbonate. 4.4 barium chloride (BaCl2 · 2H2O, 226Ra specific activity of less than 2.0 × 10-2Bq/g). 4.5 mannitol. 4.6 hydrochloride (ρ1.19g/mL). ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 13073-2010_English be delivered?Answer: Upon your order, we will start to translate GB/T 13073-2010_English as soon as possible, and keep you informed of the progress.
